Abstract
Nutting1,2 has proposed, and Scott Blair and Coppen3,4, Broome and Bilmes5,6, Couzens and Wear-mouth7, Lethersich8 and Haward9 have developed and applied, an equation expressing the shear strain (σ) in soft materials as proportional to a power (β) of the shear stress (S) and also to a power (k) of the time (t) of its application. This equation may be written:
